چکیده انگلیسی
Sodium aluminate has been used as the aluminium precursor in the synthesis of mesoporous aluminophosphate where cetylpyridinium chloride (CTPC) was used as structure directing agent. Synthesis of the materials was performed in a broad range of pH from 3 to 10. The obtained materials were characterized by using XRD, TEM, ICP, nitrogen sorption isotherms, solid state NMR, TG-DTA and FTIR. The samples prepared at pH 5-8 were thermally stable up to 450 °C and presented specific surface areas in the range of 420-640 m2 gâ1 after calcination for removal of the surfactant material. TEM image revealed the obtained mesoporous aluminophosphate possessed disordered porous structures. DH analysis derived from the adsorption branch showed that the average pore size of the sample was 2.6 nm in the 5-8 pH range.
